CENTRIFUGAL CASTING-MACHINE.

Application filed May 7, 1915. Serial No. 26,486.'

To all whom it may concern:

Be it known that I, WILLIAM H. lWlLLS- rAUeII, a citizen of the United States ofbad to the accompanying drawings, forming a part thereof.

My invention relates to metal foundmg and particularly to such casting apparatus or molds as are adapted to be rotated while the casting material is being introduced.

One object of my invention is to provide a mold of the character above indicated that shall be simple and durable in construction and particularly arranged for effectively cooling the casting while it is sub]ected .to-

centrifugal force.

Other objects and advantages of my invention will be set forth hereinafter, and in order that my invention may be thoroughly understood, I will nowproceed to describe the same in the following specification and then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a longitudinal elevation largely in section of a casting apparatus or mold arranged and constructed in accordance with my invention. a

Fig. 2 is a transverse sectional elevation taken on the line 22 of Fig. 1.

Fig. 3 is a partial transverse sectional ele-- vation in which a. modified inner cylindrical member which may be substituted for that shown in Figs. 1 and 2, is illustrated.

The mold comprises an outer cylinder 10 having flanges 11 and 12, an inner cylinder 13, an end plate 14, and rollers 15 and 16 on which the cylinder 10 is mounted, its annular flanges 11 and 12 being supported thereon. The outer cylinder 10 is furthermore provided with a gear wheel 17 and at one end with an inwardly extending flange 19. The rollers 15 and 16 are rotatably mounted on stationary brackets 18 and are flanged to cooperate with the flanges 11 and 12 and to prevent the accidental longitudinal displacement of the apparatus.

The inner cylinder 13 is closed at one end 20 and is adapted to fit into the outer cylinder 10. However, it is provided with a plurality of lugs constituting interrupted Specification of Letters Patent.

Patented Au". 7, 1917.

'or lugs 25 which engage the end of the outer cylinder 10 and keep the bottom 20 of the inner cylinder at a fixed distance from the flange 19.

. The end plate or disk 14 has a central opening 26 and is secured to the outer cylinder 10 by means of studs 27 and nuts28, the arrangement of parts being such that the disk serves to clamp the inner and outer cylinders together since the flaiige 24 extends between the disk and the end of the outer cylinder as clearly shown in Fig. 1.

Between the flange 19 and the end of the inner cylinder is formed an annular inlet passage 30 which communicates with the cooling chamber 23 and to which water or some other suitable cooling fluid may be supplied through a stationary pipe 31 having a curved end as shown at 32. When the mold is rotating this cooling fluid is forced centrifugally into thepassage 23 and is thrown outwardly at the opposite end through the spaces between the lugs 25 between the flange 24 and the end of the outer cylinder 10. In order to receive the "fluid as it is discharged from this passage, an annular channel or trough 34; is provlded having an outlet 35.

The inner cylinder 13 may be formed in various ways depending upon the form of casting desired. It may, for example, be

provided with' a plurality of longitudinal ribs 36 as shown in Fig. 2 which divide it into a plurality of pockets 37 in which reetangular billets or bars may be cast On the shaft 11.

The apparatus described is particularly adapted for casting chilled rolls, the cooling fluid being adapted to dissipate the heat from the casting metal. It is, however, equally applicable for the casting of billets,

. this adaptation being shown in Fig. 2 of the drawings.

The machine is used in a well known manner,- metal being poured through the opening 26 when the mold is in rotation.

It is obvious that various structuralmodifications ma be effected within the spirit and scope o my invention. I therefore intend that only such limitations be imposed as are indicated in the appended claims.

What I claim is: I

1. A casting apparatus comprising an outer rotatable member, an inner mold secured thereto and spaced therefrom to provide a coolin chamber, and means for circulating coollng liquid therethrough.

2. A casting apparatus comprising an outer rotatable member, an inner mold secured thereto and spaced therefrom to provide a cooling chamber and means .dependout upon the rotation of the outer member for circulating cooling liquid through the cooling chamber. 7

8. A casting apparatus comprising a hollow cylindrical outer member, means for rotatively supporting said member, an inner cylindrica mold spaced from the inner surface of the outer cylinder toprovide a cooling chamber between them, said outer c linder' having an inwardly extending ange forming an annular inlet channel adjacent to one end of the inner cylinder'for the reception of-a cooling liquid.

4. 'A casting apparatus comprising a hollow cylindrical outer member, means for rotatively supporting. said member, an inner cylindrical mold spaced from the inner surface of the outer cylinder to provide a cooling chamber between them, said outer cylinder having an inwardly extending flange forming an annular inlet channel for said chamber ad'acent to one end of the inner cylinder an said inner cylinder having an outwardly extending flange at its other end spaced from the adjacent end of the outer cylinder and forming an annular outlet passage.

spaced from said inwardly extending. flange of the outer cylinder to provide at one end an annular inlet channel, and an outwardly extending flange near the other end of the inner cylinder spaced axially from the adjacent end of the outer cylinder, whereby an outletchannel is formed between said flange of the inner cylinder and the adjacent end of the outer cylinder.

6. A casting apparatus comprising a hollow cylindrical outer member having an in wardly extending flange at one end, and a pair of spaced outwardly extending flanges, rollers adapted to engage the outwardly extending flanges and rotatively support said member, an inner cylindrical mold spaced from the inner surface of the outer cylinder to provide a cooling chamber between them and spaced from said inwardly extending flange of the outer cylinder to provide at one end an annular inlet channel, an outwardly extending flange near the other end of the inner cylinder spaced axially from the adjacent end of the outer cylinder, whereby an outlet channel is formed between said flange of the inner cylinder and the adjacent end of the outer cylinder, and a cooling fluid supply pipe arranged v to discharge in a radial direction into the-- a inlet channel.

7 A casting apparatus comprising a hollow cylindrical outer member having an inwardly extending flange at one end, and a pair of spaced outwardly extending flanges, rollers adapted to engage the outwardly extending flanges and rotatively support said member, an inner cylindrical mold spaced from the inner surface of the outer cylinder to provide a cooling chamber between them and spaced from said inwardly extending flange of the outer cylinder to provide at one end an annular'inlet channel an outwardly extending flange near the other .end of the inner cylinder spaced axially from the adjacent end of the outer cylinder, whereby an outlet channel is formed between said flange of the inner cylinder and the adjacent end of the outer cylinder, and a cooling fluid supply pipe arranged to discharge in a radial direction into the inlet chamber, and a relatively stationary annular channel having an outlet opening and adapted to receive liquid from said outlet channel.

8. A casting apparatus comprising a hollow cylindrical open-ended "outer member having an inwardly extending flange at one ,end, means for rotatively supporting said member, an inner cylindrical mold closed at the end adjacent said .inwardly'extend-" ing flange, spaced from the inner surface of the outer cylinder to provide a cooling chamber between said cylinders and with its closed end spaced from the inwardly extending flange of the outer cylinder to provide I .at one end an annular inlet channel, and an outwardl end of t e inner cylinder spaced axially from the adjacent end of the outer cylinder, whereby an outlet channel is formed be- 7 tween said. flange of the inner cylinder and the adjacent .end of the outer cylinder.

9. A casting apparatus comprising a hollow cylindrical open-ended outer member having an inwardly extending flange at one end, means for rotatively supporting said extending flange near the open member, an inner cylindrical mold closed at the end adjacent said inwardly extending flange, spaced from the inner surface of the outer cylinder to provide a cooling 5 chamber between said cylinders and with its closed end spaced from the inwardly extending flange of the outer cylinder to provide at one end an annulariinlet channel, an outwardly extending flange near the open 10 end of the inner cylmder spaced axially from the adjacent end of the outer cylinder, whereby an outlet channel is formed between said flange of the inner cylinder and the adjacent end of the outer cylinder, and a stationary annular trough surrounding said outlet channel.

In witness whereof I have hereunto set my hand this 6th day of May, 1915.
